To all whom t may concern: for strengthening purposes, Va series vof braces Be it kn'own that fl, `OvID MINER GoULD, of c connect the lattice frames rigidly together, the cityofMontreaLProvinceof Quebec, Canand a Water supplying box m with a water ada, have invented certain new `and useful supplying pipe n leading thereinto and a se- Improvements in Water-Cooling Towers. ries of discharge pipes n leading therefrom, is l My invention has for its object to provide located above the distributing platform,

The interlaced wires of the The main advantages of the bars are that lattice work are preferably arranged in pairs they present a great area of surface over` which the water spreads, which has the effect not only of thinning the stream out into a film but also retarding its flow while the roughness of the surface increases the resistance offered to the iilm and consequently further retards its flow and with the increased area increases the time in which it is subjected to the evaporating and cooling action of the air,

What l claim is as follows:-

l. In an aerating and cooling device, a ietarding bar having a central upwardly extending projection upon its top, the base of the said projection being of less width than the top of the said bar for the purpose of presenting a substantially horizontal surface at each side of the projection, and a pair of separated downwardly extending projections upon the bottom of the bar.

2. ln an aerating and cooling device, a retarding bar having a central upwardly extending projection upon its top, the base of the said projection being of less width than the top of the said bar for the purpose of presenting a substantially horizontal surface at each side of the projection, a pair of separated downwardly extending projections upon the bottom of the bar, and a pair of angular aerating and cooling surfaces leading from opposite sides of the said top to the said lower projections.

3. ln an aerating and cooling device, a retarding bar having a central upwardly extending projection upon its top, the latter exceeding in width the said projection, and a pair of separated downwardly extending projections upon the bottom of the bar, and each located inward from the side edges of such bar, and a pair of angular aerating and cooling surfaces leading from the said side edges to the said lower projections.

4. ln an aerating and cooling device, a retarding bar presenting converging sides terminating in a bottom and having a member of triangular cross-section secured along the middle of the top thereof the base of such triangular member being of less width than the said top to present a pair of retarding surfaces one on each side of the middle triangular member, and a pair of members of triangular cross-section secured a short distance apart along the said bottom and forming a continuation of the said converging sides.

5. ln a water cooling tower the combination with a plurality of aerating and cooling I bars each presenting an angular apex extending throughout its length for dividing a l stream falling upon such apex, and means l maintaining such division during the -fall of the water throughout the tower, of a water distributing platform made up of a series of separated boards with the'spaces therebetween located over the apices of the bars, and means dividing the water falling through such spaces and causing the same to 'fall upon opposite sides of the said apices.

6. ln a water cooling tower the combinationwith a plurality of aerating and cooling bars each presenting an angular apex extending throughout its length for dividing a stream 'falling upon such apex, and means maintaining such division during the fall of i the water throughout the tower, of a water distributing platform made up of a series of separated boards with the spaces therebetween located over the apices of the bars, and angle irons dividing the water falling through such spaces and causing the same to 'fall upon opposite sides o'f the said apices.

7. A water cooling tower comprising a pair of lattice-work frames, a plurality of aerating and cooling bars supported by such latticework and each presenting a longitudinal apex of angular cross-section, the sides of each bar converging downwardly and the lower ends thereof being separated by an. upwardly extending recess, a water distributing platform supported above the said bars and having a plurality of creviees parallel to and in vertical line with the bars, a plurality of angle irons, and means supporting such angle irons in valvular relation to the said crevices.

8. A water cooling tower comprising a pair of wire lattice-work frames, a plurality of aerating and cooling lattice-work and each presenting a longitudinal apex of angular cross-section, the sides of each bar converging downwardly and the lower ends thereof being separated by an upwardly extending recess, a water distributing platform supported L bove the said bars and having a plurality of crevices parallel to and in vertical line with the bars, a plurality of angle irons, and adjustable means supporting such angle irons in valvular relation to the said crevices.
